Maybe ten-year-old Elizabeth put it best when she said to her father. “But Dad, you can't be healthy if you're dead.”
Dad , in a hurry to get home before dark so he could go for a run, had forgotten to wear his safety belt--a mistake 75% of the US population make every day. The big question is why.
There have been many myths about safety belts ever since their first appearance in cars some forty years ago. The following are three of the most common.
Myth( 神话)Number One: It's best to be “thrown clear” of a serious accident.
Truth: Sorry , but any accident serious enough to “throw you clear” is also going to be serious enough to give you a very bad landing. And chances are you'll have traveled through a windshield(挡风玻璃)or door to do it. Studies show that chances of dying after a car accident are twenty-five times greater in cases where people are “thrown clear.”
　　Myth Number Two: Safety belts “trap” people in cars that are burning or sinking in water.
　　Truth: Sorry again. but studies show that people knocked unconscious(昏迷) due to not wearing safety belts have a greater chance of dying in these accidents. People wearing safety belts are usually protected to the point of having a clear head to free themselves from such dangerous situations, not to be trapped in them.
　　Myth Number Three: Safety belts aren't needed at speeds of less than 30 miles per hour
　　Truth: when two cars traveling at 30 mph hit each other. An unbelted driver would meet the windshield with a force equal to diving headfirst into the ground from a height of 10 meters.

A town in Oxfordshire has become the first in the UK to have biomethane（生物甲烷）gas from human waste piped to their homes for gas central heating and cooking.

Up to 200 families in Didcot now receive the gas via the national gas power system. Head of energy and technology at British Gas, Martin Orrill, said customers wouldn’t notice any difference as the gas is purified（提炼）to the highest standard and has no smell. The gas is produced at a sewage（污物）treatment works plant in Didcot.

The entire process takes only less than three weeks, with the sewage being collected and sent first to settlement tanks. The solid waste material is then fed into digesters, where anaerobic bacteria（厌氧菌）digest the sewage, with the aid of enzymes（酶）to speed up the process. The digestion process produces methane, which can be burned to drive machines to produce electricity, or can be purified and fed into the gas network and piped to homes and businesses. British Gas says supplying the gas rather than electricity is far more efficient since around two-thirds of the energy is lost in producing electricity.

Partners in the Didcot project, British Gas, Scotia Gas Networks, and Thames Water, all hope to expand the process to other towns, and other companies such as Ecotricity and United Utilities have also announced biomethane projects being planned. One of these projects, in Manchester, could be supplying 500 homes with biomethane by mid next year. Another British Gas project in Suffolk will provide gas from digestion of brewery wastes to around 235 families.

The Didcot project cost ￡2.5m and was influenced by promises of government aids aimed at encouraging companies to develop renewable technologies. An EU directive means the UK must ensure at least 15 percent of its energy is from renewable sources by 2020.

    The UK produces about 1.73 million tons of sewage annually. If all sewage treatment works in the UK were fitted with the technology, they could supply gas for up to 350,000 families.

1.Which of the following is true of the biomethane gas?

   A. It’s mainly made from rotting plants.

   B. It’s an environmentally friendly gas.

   C. Its production process is too long.

   D. It’s easily recognized by the customers.

2.What is the function of the enzymes?

   A. To digest the solid waste material.

   B. To help get rid of anaerobic bacteria.

   C. To help purify the biomethane.

   D. To speed up the digestion process.

3.According to British Gas, the biomethane gas had better be used _____.

   A. as the power for the vehicles                                   

   B. for the heating and cooking

   C. to produce the electricity                                          

   D. to drive a variety of machines

4.The last three paragraphs mainly show that _____.

   A. UK government supports the biome thane projects

   B. the biome thane projects are very costly

   C. the biome thane projects still face many barriers

   D. the biome thane projects are promising

5.What should the text belong to?

   A. Computer science.                  B. Engineering.         C. Energy.                  D. Business.

 

Back those photos up

The images were striking. Homes on the East Coast were washed away by Super storm Sandy. People were in tears, picking up faded photographs, among their only remaining possessions.

If that doesn’t move you to get serious about safekeeping your lifetime of memories, what will? The digital age offers tools never imaginable before—including one-click access to a lifetime of family photos.

Here is a brochure on how to back up (存) your photos and save them online, where they can live forever and be accessible in good times and bad.

Scanning

The first step for those old photos is to scan them and save them to a digital format. Most printers come with scanners these days, so that’s an easy but extremely time-consuming step.

Storing the photos

With your scans in place, import the photos into your computer, and back them up.

You could make multiple copies of the disks and spread them to loved ones. Or you could choose external(外接的) hard drives or USB thumb drive, and add your photo and video collection from your computer. 

Online backup

If you need lots of space, look at a pure online backup service, Caronite.     

Caronite backs up 300 million files daily. Once you sign up, it starts to pick up everything you have on your hard drive. But photo collection on your computer’s main hard drive charges for $59 a year.

Cloud Storage

For folks who don’t need automatic backup, but instead want to take a more active approach, Dropbox, Google Drive and Microsoft’s Sky Drive let you store files online by yourself, share and instantly access them. All offer free options—2GB of free storage for Dropbox, 5GB for Google and 7GB for Sky Drive. But if you want more, you need to pay.

Bottom Line

The hard drive or flash drive is the cheapest and easiest. But drives can fail. Online services are more expensive, but more secure. With more of us switching back and forth between our computers, such services are the best way to get access to our data from wherever we are. 

1.Why does the author mention Super storm Sandy?

A. To tell the background of the scanning photos.     

B. To describe a severe natural disaster.

C. To attract the readers’ interest in the backups.       

D. To win the readers’ sympathy.

2. What can we know from the passage? 

A. Scanning photos take little time but costs a lot.  

B. Caronite charges for backing up photos from hard drive.

C. Google Drive offers unlimited free photo storage on line.

D. The hard drive or flash drive is the cheapest and safest.

3. Which of the following allows storing files automatically?

A. Dropbox.         B. SkyDrive.     C. Caronite.     D. Flash drive.

4.The main purpose of the passage is to _____.

A. introduce some of the storage services

B. tell real stories about storage services 

C. describe the functions of storage services    

D. argue about the advantage of storage services
